I agree... I've setup a support email address that users send all requests to - this is the email account that Spiceworks monitors. Then, in the settings, I have both my work email associated with my Spiceworks User account and also an additional account that shoots a text message to my Blackberry.

This way, I get an email and a page when receiving a new request. If you centralize in this way, users will get used to sending all IT Requests to your new account. For me, requests and tickets are so much easier to manage in this way...

Our ISP provides our email (POP3). I'm using this at work. Initially I just wanted SW for it's inventory feature. We have around 70 computers in 5 offices. It's not like computers are breaking every day, but I think the help desk is a cool feature.
